PRIMING MECHANISM FOR INTERNAL-COMBUSTION ENGINES.

Specification of Letters Patent.

Patented July 30, 1918.

Application filed May 17, 1916. Serial No. 98,168.

To all whom, it may concern:

Be it known that 1, Emma I. KuAY, a citizen of the United States, residing at North Yakima, in the county of Yakima and State of lVashington, have invented certain new and useful Improvements in Pruning Mechanism for Internal-Combustion Engines, of which the following is a specification.

My invention relates to priming mechanism for internal combustion engines.

While the invention aims to generally im prove, simplify and render mechanism of this nature more efficient and still maintain the cost of manufacture and upkeep at a low figure, yet I particularly aim to provide mechanism of this nature capable of use in connection with a plurality of cylinders of the engine; mechanism having a supply conduit, a shaft therein, a crank on the shaft and a dislodging member operable by the crank to engage the valve of a priming cup; to provide a particular form of priming cup to cooperate with the improved priming mechanism; to provide an improved means to control the discharge of the gasolene into the conduit, and to provide a device of the construction hereinafter set forth possessing the additional objects and advantages to be pointed out in relation thereto as the description progresses, and which is to be taken in connection with the accompanying drawings illustrating one preferred embodiment.

In said drawings Figure 1 is a view showing my improvement in connection with an internal combusthe latter being shown in vertical section;

" Fi 2 is a view of m 1 im rovements on a larger scale than Fig. 1, mostly in vertical section and including a fragment of theinternal combustion engine;

Fig. 3 is a cross sectional view on the line 3-3 of Fig. 2;

Fig. 4f is a cross sectional view on the line -t l of Fig. 2;

Fig. 5 is a vertical. sectional view particularly illustrating my specific form of priming cup, and

Fig. 6 is a view illust 'ating the indicator means employed in side elevation.

Referring specifically to the drawings, wherein like reference characters designate like or similar parts in the views thereof, an internal combustion engine is conventionally represented at 7 having any desired number of cylinders 8. 7

To facilitate priming of the cylinders h, I preferably provide a novel form of priming cup as specifically illustrated in Fig. 5 which has a flared or funnelshaped receiving cup 9 integ :11 with and extending from an inlet tube at 10 screw threaded to the engine structure at 11. The wall of tube 10 is preferably cut away to provide a housing 11 for a spring of the expansion type 12 and a shoulder 13 on which it rests, and as well, a closure valve 14 having a beveled edge and urged to its seat, which is a flange 15 having a beveled face corresponding to that of the valve, by the said spring 12. The valve H is adapted to be depressed against the tension of the spring 12 so that gasolene from the cup 9 may flow into the cylinder 8.

The gasolene or priming fuel may be provided from a tank 16 of any desired configuration and mounted at any suitable location. However it is disposed as shown for example, in Fig. 1, in front of the dash board of the vehicle for which the engine acts as the propelling medium and which dashboard is shown at 17. Connected with the dashboard is the usual board 18, in advance thereof, which serves as one support for the engine hood.

Integral with the tank 16 is a collar 19 to which a manifold or supply conduit 20 is screw threaded as shown in Fig. 2. This manifold is closed at its outer end by means of a cap 21 which screws thereon as at 22. Extending into each cup 9 and depending integrally from the manifold 20 is an outlet tube 23.

Extending through one wall of the tank 16 is a shaft or rod 24 which is journaled for rotation in said wall and also in a bearing 25 formedintegral with the cap 21. The rod 24 is provided with a suitable number of cranks 26 on each of which a valve depressor or mover rod 27 is pivoted as at 28. i

The portion of the tank 16 opposite the manifold 20 is provided with a suitable number of ports 29 to permit the flow of gasolene from the tank 16 into the conduit 20. Rigidly mounted on the rod 24 and disposed on opposite sides of the wall of the tank where said ports 29 are provided, are valve plates 30 having ports 31 adapted to register at suitable times with the ports 29.

Within the tank 16 a couplingin the form of a nut 32 may connect a rod 33 with a rod 24 for movement therewith and which rod 33 is journaled in one wall of the tank 16 and the dashboard and extends beyond the latter and through an indicator plate 34 mounted on the said dash board. Beyond the indicator plate, the rod 33 has an indicator 35 rigidly connected thereto and at times adapted to point to the cleln'ieation off thereon and the delineation on thereon.

Rod 24 may be turned or rocked manually by engagement with a crank 36 extending therefrom and through a circumferentially elongated slot 37 provided in the top wall of the manifold but so as not to permit the escape of gasolene passing through the manifold. v

When it is desiredrto admit a priming charge of gasolene or other fuel from the tank 16 into the cylinders 8,'the crank 37 is turned so as to shift the rods 24 and 33 and bring the ports 31 into registry with the ports 29, and so as to bring the elements 27 into engagement with the valve 14 anddepress them out *of engagement with their seats 15; With the parts in this position, the fuel will flow through the ports 29 and 31 into the manifold 20, through the tubes 23 into the cups 9, past the valves 1 14, through the tubes 10 and into the cylinders 8. l/Vhile the parts are'in this. position, the indicator 35 points to on delineated on the plate 34. When the desired eharge has been a'dmitted,'crank 37;..is released whereupon the springs 12 will urge the valves 14 to their seat and close the priming cup .and as well drive or force the rods 27 upwardly and accordingly shift the shaft 24 to such an extent that the ports 29zand31 will be out of *alinement and the supply of'gasolene cut off as a result. The rod 33,.will also. move with the rod24 and move the indicator 35 to the position" shown in Fig. 6 where it points to off. delineated on the plate 34. I

It is to be understood that the valve means at 30 may be varied if desiredand that as well, other changes in the detailsgof construction may be resorted to without departing from the spirit and scope of m-y invention since merely one embodiment has been shown. i 3' 1.
